Take the sounding of the astral bell, which dozens of us have heard indoors and
out of doors, morning, noon and night, close to us and far away up in the air --- when
large parties were gathered together, and when we have been alone in the room in which
Madame Blavatsky was, and on at least two occasions in rooms more or less distant from her
--- caused by the exercise of her own powers, according to her statement, at times when we
were waiting to hear it, and caused by the Brothers, according to her account, to attract
her attention, at times when we were not in the least expecting it, and when she was in
earnest conversation with us, herself speaking, on one occasion at any rate, when the bell
rang out.

The sound, by the way, is quite sui generis. You can most nearly
imitate it by striking the finger wetted on the edge of a finger-glass half full of water,
and drawing it for a second along the edge.
